Cube tricks of same digit number 14 lesson on mathematics Tricks and Fun Hello friends today we are going t o study the methods to find cube of same digit numbers.I am Dr Prema B Sejekan. We can use a special method to find the cube of these numbers.   Cube of unit digits   1.    1              6.              216  2     8              7.              343  3    27             8.              512  4    64.            9.              729  5    125.         10.            1000   First count the numb...

 Cube-Tricks,13thLesson-MathematicsTricks-and-Fun   Today we are going to study the methods to find cube of numbers.I am Dr Prema B Sejekan. We shall study methods using yavadunam sutra to find the cube of numbers. We should learn and keep ourselves ready with the square and cube of unit digits for a quick solving of the cubes of numbers..Here I have noted down the squares and cubes of commonly used digits.   In finding cube of a number,first   find the number of digits in the question and3/(3-1) times that will be the number of digits in the answer and   when first digit is 1,2,3 it will be    3-1,3-2 times digits , in the answer.  Mark the expected digits in the answer as dots.    This is Cubing by yavadunam tavadunokritya varge cha yojayet . Here cube of 103 is t he question.Here the base is 100.  3 is the excess and the main working digit is 3 here we multiply 3 with 3 which stands for the cube so 3 X ...

12-lesson-mathsTricksandFun-cube solution     Today we are going to study the methods to find cube of numbers. I am Dr Prema B Sejekan . Cube of a number is the product of multiplying by itself thrice. Though there are different methods three methods ie Anurupya sutra yavadunam sutra, and method to find the cube of same digit numbe rs is discussed in these lessons on cubing We should keep ourselves ready with the s quare and cube of unit digits for a quick solving of the cubes.Here I have noted down the squaring and cubing of commonly used digits. Cubing by Anurupya Sutra is the topic to study here.algebraic explanation in this is a+b whole cubed is equal to A3 3a2b 3ab2 and b3. This is used to find cube of 2 digits .     In finding cube of a number,first   find the number of digits in the question and 3/(3-1)times this  will be the number of digits in the answer and   when first digit is 1,2,3 this m be 3-1/-2 times the se digits , in t...

10th lesson of Mathematics Tricks and Fun In this lesson on Urdhwa Tiryagbhyam Sutra, we will study multiplication of big numbers where digits are in random. This is also useful for squaring of such numbers . Now what is Urdhwa Tiryak Sutra? Urdhwa Tiryak Sutra is the general formula applicable to all cases of multiplication . It is also useful in the division of large numbers by another large number . Only multiplication part will be taught in this lesson. All arithmetic numbers are algebraic expressions in X with X equals 10. The calculations can be explained with algebraic principle, which willbe done at a later stage .Urdhwa Tiryak process of vertical and crosswise multiplication can be mastered easily, after studying a few examples. in the first example, 28 x 46 first we multiply the digits on the tens place straight. 2 x 4 is 8. we are multiplying totally four digits the answer will have three or four digits . since 8 is a single digit we will write as 08 at the edge. ...

       11th Lesson of  mathematics tricks and fun       Hello friends ,today we are going to stud y Nikhilam Sutra in multiplication. I am Dr Prema b sejekan.  Nikhilam Sutra says Nikhilam Navatascharamam Dasatah.Means All from Nine and Last from Ten . Nikhilam sutra has upasutras corollaries and sub-corollaries.All of them and their application  in multiplication will be discussed here.  Here  applications of Nikhilam Sutra in general is shown.Let us take the first among the 7 examples. In this, the first question is  9 times 9.working base is 10 . So complement of 9 from 10 is 1.   1×1 is 1 and  9-1 is 8. The answer is 81.2nd example is 7× 6 , so complement of  7 from 10 is 3. Complement of 6 is 4 so we will write 7-3× by 6-4 so ,3×4 is 12 and 7-4,is 3 .Adding the carry overs answer is 42.  Rest all examples are with different bases ie  100,1000 base  done in the similar way. ...
